Responsive News Page with Slide-out Menu

What are you most proud of, and what would you do differently next time?

This was my first attempt at a sliding menu, and I think it looks/works great. Next time I might attempt a more complex transition animation.

What challenges did you encounter, and how did you overcome them?

The links in the sliding navbar would remain on the main page after the navbar had been collapsed. Eventually I realized that overflow: hidden would take care of the problem.

What specific areas of your project would you like help with?

Responsiveness, design accuracy, and functionality. Thanks!
